    EGR(Exhaust Gas Recirculation) & SCR(Selective Catalytic Reduction)

    There have been two approaches to regulatory compliance: EGR and SCR. EGR was implemented January 1, 2007 and SCR was implemented January 1, 2010. EGR was able to meet the Federal Standards for 2007, but not able to meet the new standards for 2010. In 2007 the Emissions Standard was 1.2 NOx (g/hp.pr) and it could be reached using EGR technology, but January 1, 2010 this standard dropped to .02g/HP...

    Existing AdBlue Quality Standards

    In the international standard defining DEF (ISO 22241), it is referred to as AUS 32 (aqueous urea solution 32%). DEF is also sold as AdBlue, a registered trademark of the German Association of the Automotive Industry. Several existing standards for urea for major vehicles are as follows ; 1. International Organization for Standardization ISO 22241-1:2019 Diesel engines — NOx reduction agent AUS 32...

    Importance of AUS40 for ship

                         China's economy continues to develop rapidly and the demand for oil resources continues to grow in recent years. According to statistics, China's oil consumption in 2013 was about 490 million tons, resulting in more and more significant air pollution. The severe haze in winter in some cities of China has become more and mo...

    Precautions for using AdBlue in winter

    AdBlue will freeze at - 11 ℃ ,so AdBlue hose and pump are likely to freeze in cold areas . We have mentioned that the AdBlue with 32.5% concentration is the most ideal cause AdBlue working at this concentration can reduce the NOx to the greatest extent. Too high or too low concentration will reduce the reduction of NOx. However, it should be noted that the concentration of AdBlue is greatly affect...

    AdBlue® Diesel Exhaust Fluid (DEF)

    The need to control toxic emissions from diesel combustion engines is ever-increasing. AdBlue® are being developed to manage the output of poisonous gas like nitrogen oxide(NOx) from engine exhaust systems. Selective Catalytic Reduction(SCR) is a method of controlling nitrogen oxide emissions. This process requires diesel exhaust fluid, namely AdBlue®, to be injected into the exhaust pipe ...

    AdBlue® reduce emissions

    Reduced raw exhaust emissions are achieved in TDI engines equipped with AdBlue® through an advanced, modified fuel injection system, exhaust gas re-circulation and optimised turbocharging. The AdBlue® solution is stored separately from the fuel tank and is pumped in small quantities into the exhaust pipe ahead of the DeNOx catalyst when the engine is running. The quantity of AdBlue® in...

    Urea Tank on Truck

    Urea tanks is the storage tanks for urea solution, which contain urea solutions and are mainly used in trucks and buses. The emissions have reached the national IV standard after the vehicle exhaust passes through the urea tank .Usually the tank with the working temperature range from-40 to + 85 ℃ and volume range from 10L to 80L. Material and structure:  the tan...

    Refill the DEF tanks

    From 2013, trucks and diesel engine cars have been created to allow users to refill their own DEF tanks. As a result, a number of truck stops and gas stations have begun offering a DEF pump next to the diesel fuel pump. You may even purchase small quantities—or order large containers for commercial use—to keep at home. Although safe to handle and non-toxic, AdBlue® can eat through some metals....
